CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 358,872, dated March 8, 1887.

Application filed July 9,1894. Renewed February 3, 1887. Serial No.226,429. (No model.)

HALL, of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Railway Axle Boxes and.

Journals, of which the following is a specification.

It is well known that the ordinary axle-box is liable to become hot from the friction of the to journal therein when the latter is run for any considerable length of time, and that for this reason there is agreat waste of lubricating material, a rapid deterioration of the journal and box, a waste of power, and in many cases great danger of setting fire to the car from the ignition of the lubricating material by the high heat generated in the box, as aforesaid.

The object of my invention is to avoid these dangers and drawbacks by providing means for maintaining the journal and its box constantly at a low temperature; and my invention comprises certain novel combinations of parts, whereby said objects are secured.

Figure 1 is a vertical transverse sectional view of a railway'ear provided with my said invention. Fig. 2 is a longitudinal vertical sectional View, and Fig. 3 avertieal transverse sectional view,on a larger scale, of certain parts or elements of the combinations included in my said invention, said parts or elements not being so fully shown in Fig. 1.

A is the shell of the journal-box. B is the box itself, placed upon the journal or bearing 0 of the axle D. The relative arrangement of 3 5 these parts with reference to each other, to the truck or wheeled portion of the car, and to the body or platform of the car need not differ ma terially from that of the corresponding parts of an ordinary car.

0 The box 13 is hollowed or internally chambered-that is to say, it is constructed with a chamber, E, the inner side of which is substantially concentric with the bearingsurface of the box-in other words, with the journal 5 or bearing 0 placed therein, and is separated from said journal or hearing by a thin shell or plate-like wall, a. In order that this inner portion or wall, a, of the box may be suitably stiffened, radial braces b extend from said wall c to the opposite side of the chamber, as shown in Figs. 2 and 3. At one side or part the chamber E is provided with one or more inlet pipes or passages, 0, and at another side or part, preferably opposite, is provided with one or more outlet pipes or passages, d. The inlet and outlet pipes or passages, one or both, may be provided with cocks f, to regulate the quantity or velocity of the water or other fluid passed into or through the chamber E, as hereinafter more fully set forth.

The inlet or inlets c of the box are connected by a pipe or hose, F, with a tank or reservoir, G, so placed that the liquid contents of the tank or reservoir G may be caused to pass into the chamber E, and thence out therefrom through the outlet or outlets (1. Of course the several boxes for the several wheels of the car may connect with and be supplied from one and the same tank or reservoir.

The tank G is supplied with water at ordi- 7o nary or at any suitably low temperature, or with any appropriate refrigerating or cooling fluid. The water or other fluid enters and passes through the chamber E, being separated from the wearingsurface of the box and from the journal or hearing by the relatively-thin wall a, substantially concentric with the adjacent upper half of the journal. The heat generated from the rotation of the journal in the box passes as fast as generated from the jour- 8o nal and from the wearing-surface of tlie'box through the shell or plate-like wall a, and, be ing absorbed by the water or cooling-fluid passing through the chamber E, is carried off thereby, so that the journal and box are both 8 5 prevented from becoming heated, and all the mischievous results of heating are thereby effectually avoided.

I am aware that it has heretofore been proposed'to cool railway-journals by a circulation of water through narrow pipe-like channels formed in the journal-box; but such devices are devoid of the shell or plate-like inner wall,

a, hereinbefore described as a peculiarly advantageous element in my said invention, and 5 which enables my said invention to remove the heat from the journal with greater rapidity and certainty than has heretofore been found practicable, and which insures the retention Thecombinationoftheinternally-chambered of a lower and harmless temperature in the box 13, constructed with a thin shell or platejournal and journal-box. like inner Wall, a, substantially concentric with 20 So far as concerns the internally-chambered the bearing-surface of the said box, inlet and 5 bOX B havingan innerplate-likewall, a, which outlet pipes or passages for the transmission is substantially concentric with the bearing, of Water through the said box and upon and and inlet pipes or passages for the transmisacross the inner surface of the walla, regulatsion of water through the chamber of theboX, ing cook or cocks f, journal or bearing 0 of a 25 considered as a separate and distinct device, car-axle, a tank or reservoir, G, pipe or hose 10 the same is shown and duly claimed in my F, and shell A, all substantially as and for the separate and distinct application for Letters purpose herein set forth.
